Abstract EN
Sr4Si3O8Cl4:Eu2+ blue-green phosphors were synthesized by the gel-combustion method.
The as-synthesized phosphors were analyzed and characterized by X-ray diffraction and fluorescence spectrophotometer.
The results indicate that orthorhombic phase Sr4Si3O8Cl4:Eu2+ has been formed after the precursor calcined at 900°C reductive temperature.
The excitation spectrum of Sr4Si3O8Cl4:Eu2+ is a broad band in the range of 250 ~ 450 nm and the main peak at 324 nm.
The emission spectrum is also a broad band with the main emission peak at about 484 nm, which is ascribed to the typical 4f5d1 to 4f7 transition of Eu2+.
Moreover, the effects of the concentration of Eu2+, the reductive temperature, and the doping amount of Mg2+ on luminescent properties were discussed.
